Why are chromatins not condensed during interphase but instead condensed at prophase of mitosis? What makes them condense at prophase?

Here's an image that explains the cell cycle:
And here's one that explains Mitosis as a subcategory of the cell cycle:
Chromosomes condense on the metaphase plate before they are pulled apart by kinetochore microtubules in a Tug-of-war. Chromosome condensation is not yet fully understood, but nucleosome structure is hypothesized to play a role. This is a very good question and is definitely not too broad.
